RoutedEvent: Adding an Event Handler (Code) with RoutedEvent's DependencyProperty

<Window x:Class="TestApp.Window1"
xmlns="..."
xmlns:x="...">
<StackPanel>
<TextBlock x:Name=”myTextBlock”/>
</StackPanel>
</Window>

Then we need to register the handler through the AddHandler() method. In this example, we do it from within the OnInitialized() function (overridden for this purpose):

public partial class Window1 : Window
{
…

protected override void OnInitialized( EventArgs e )
{
base.OnInitialized( e );
myTextBlock.AddHandler( MouseDownEvent, new RoutedEventHandler( MouseDownEventHandler ) );
}

protected void MouseDownEventHandler( object sender, RoutedEventArgs e )
{
…
}
…
}
